How does a confectioner get the word 'Brighton Rock' running through the length of a piece of Brighton Rock?

They make the letters first in candy in large size blocks (so the lettr is a cross-section of the block) and then arrange them with blocks of white candy in between (so they now have a really fat short stick of rock). Then they roll it and stretch it so the letters get smaller and stretched out and finally when it is the right thickness they harden it.
